Illusory Superiority is a cognitive bias whereby individuals overestimate their own qualities and abilities relative to others. It is sometimes called the Lake Wobegon Effect after Garrison Keller’s fictional home town in Minnesota where “all the women are strong, all the men are good looking, and all the children are above average.” The trap with this fallacy is that it prevents people from seriously examining their own skills and thus overlooking opportunities for growth. From a personal development standpoint, the Illusory Superiority fallacy can be a barrier to self-improvement on many fronts.

Avoiding this fallacy is tricky, but not impossible. One path forward is to find measurable benchmarks that personal performance can be judged against, such as national or local averages. Another approach is to seek non-bias feedback from peers, for example in the form of a 360 review. Either way, developing a critical eye regarding your own performance opens up avenues for personal improvement that may not have been recognized before.
